A sprayer includes: a container; a passage including a transparent window, a first opening, a second opening and a resonator, wherein when liquid in the container is passed through the resonator via the first opening, the liquid is emitted as a gas via the second opening; and a removable detection unit disposed outside of the passage. The removable detection unit includes: a light source for illuminating the gas in the passage; an optical sensor disposed to detect a parameter of light reflected by the gas; and a processor coupled to the optical sensor for stopping the resonator from generating the gas when the parameter is below a threshold. The passage further includes a cavity disposed on a bottom surface of the passage in front of the optical sensor, wherein when the gas in the passage contacts the bottom surface, resultant water vapour will enter the cavity.

A motorized misting hair dye applicator for dispersing a dye mist throughout the hair of a user employs a comb body having a plurality of teeth which each include an ultrasonic atomizer nozzle integral therewith. The comb body additionally includes a dye distribution system which allows stored liquid dye to be directed from a reservoir to each of the nozzles where the dye can be atomized into a mist. A momentary actuating button provides a manual switching interface which allows a user to selectively operate the dye distribution system so as to control the dispersal of dye mist from the nozzles. When a user combines this misting activity with the simple act of combing the teeth through their hair, the dye mist is dispersed throughout the portion of their hair being combed.

A fluid injector for x-ray tubes and a method to provide a liquid anode by liquid metal injection, wherein the fluid injector includes a device to inject fluid from an opening in a chamber of the device as a fluid jet generated by an arrangement to change the volume within the chamber, and includes a reservoir to store the anode material, which is fluidically connected by a pipe with the chamber of the device, where the pipe has a part formed in the fluid flow direction that is shaped to block fluid flow from the chamber to the reservoir during injection, and where the includes injecting fluid in a direction towards an electron beam and refilling the chamber with liquid metal from the reservoir.

In one embodiment, a method for manufacturing an aperture plate includes depositing a releasable seed layer above a substrate, applying a first patterned photolithography mask above the releasable seed layer, the first patterned photolithography mask having a negative pattern to a desired aperture pattern, electroplating a first material above the exposed portions of the releasable seed layer and defined by the first mask, applying a second photolithography mask above the first material, the second photolithography mask having a negative pattern to a first cavity, electroplating a second material above the exposed portions of the first material and defined by the second mask, removing both masks, and etching the releasable seed layer to release the first material and the second material. The first and second material form an aperture plate for use in aerosolizing a liquid. Other aperture plates and methods of producing aperture plates are described according to other embodiments.

A housing selectively encloses a nozzle. The housing has a body that partially defines an interior space in which the nozzle is configured to be disposed. The housing also includes a cover assembly that selectively blocks a first aperture of the body and further defines the interior space. Additionally, the housing has a piston that is disposed in the interior space and secured to the nozzle. The piston defines a gas inlet, a liquid inlet, and an outlet fluidly connected to both the gas inlet and the liquid inlet. The housing further includes a biasing member attached to the piston. The biasing member is configured to exert a biasing force that biases the nozzle to a retracted position. The biasing member is further configured such that when pressurized gas flows through the body, the biasing force is overcome such that the nozzle is disposed in an extended position.
